Lemmy’s son Paul Inder, 48, paid tribute to his famous dad, saying he was “back out on the road for a longest tour to the great gig in the sky.”

Speaking after the service, Paul told the Mirror: “It’s a great feeling to see all the out-pouring of love from everyone.

"I feel like I have gained 500 brothers from this. I’ve cried until I had no more tears left and feel like its right to celebrate my dad now.

“I feel like the grieving process has somehow been speeded up for me. I’m going to continue to be a musician, but I’m going to take a bit of time off first.”

Some fans had come a long way to pay their respects, including Johnny Moore, 35, and Kelly Bamber, 21, who had flown in from Manchester.

Mohawk-haired singer Johnny said: “We just booked the flights on Wednesday – it cost us around £1,400.

“It was a 16-hour journey, but definitely worth it. There will only ever be one Lemmy. We wanted to be here to commemorate and pay our respects.”

During the service, Grohl recounted how he had first met Lemmy at strip club called Crazy Girls and was initially too nervous to approach him.

When he finally did, Lemmy complimented him for his work as drummer of Nirvana.

The Foo Fighters frontman said: “In that moment he went from being whisky-drinking, badass rock-star to being a whisky-drinking, badass rock-star with a heart.”

Grohl said Lemmy was such a fixture in The Rainbow they would, “order two Jack and Cokes, and the waitress would bring two Jack and Cokes – and his mail”.

Slash was credited at the service for helping Lemmy’s rehabilitation and getting him back on stage after he had a heart defibrillator fitted in 2013, staying by his side every day and encouraging him to keep touring.

The musician – who has recently re-joined Guns N’ Roses – explained how he first met the famous bass player at a London recording studio in 1987.

He said: “This guy had an image of being very hardcore. We had an image of being hardcore, too, but I was nervous.

"I walked in and was very graciously accepted by Lemmy and we have been friends ever since."

Metallica drummer Lars Ulrich told how he had followed Motorhead around California in 1981 as a fan and had been taken under Lemmy’s wing.

Lars added: “He made me want to be in a band, be a musician and be part of a crazy travelling rock ’n’ roll circus.

Fans were asked to stay away from the funeral, but encouraged to head to The Rainbow, where they watched, laughed and cheered as it was broadcast on the bar’s TV screens.

The service, held on Saturday, ended with a bass being plugged into an amp and turned on so it filled the room with feedback as Todd Singerman, Motorhead’s manager, announced: “Lemmy has left the building.”
